ColorspaceConversion

Synthèse

Converts the color model of a three-band unsigned 8-bit image from either the hue, saturation, and value (HSV) to red, green, and blue (RGB) or vice versa.

Discussion

For more information about how this function works, see the Color Model Conversion raster function.

The referenced raster dataset for the raster object is temporary. To make it permanent, you can call the raster object's save method.

Syntaxe

ColorspaceConversion (raster, {conversion_type})

Paramètre	Explication	Type de données
raster	An unsigned 8-bit pixel type input raster.	Raster
conversion_type	The color conversion type to perform. rgb_to_hsv—RGB to HSV hsv_to_rgb—HSV to RGB (La valeur par défaut est rgb_to_hsv)	String

Valeur renvoyée

Exemple de code

ColorspaceConversion example 1

This example applies the Colorspace Conversion function to the input raster.

from arcpy.sa import *
out_hsv_3bands = ColorspaceConversion("slope_rgb_3bands.tif", "rgb_to_hsv")
out_hsv_3bands.save("C:/arcpyExamples/outputs/slope_hsv_3bands.tif")

ColorspaceConversion example 2

This example applies the Colorspace Conversion function to the input raster.

# Import system modules
import arcpy
from arcpy.sa import *

# Set the analysis environments
arcpy.env.workspace = "C:/arcpyExamples/data"

# Set the local variables
# the pixeltype of the input raster must be unsigned 8-bit, otherwise,
# the function would fail
in_raster = "slope_rgb_3bands.tif"

# Execute ColorspaceConversion function
slope_hsv_3bands = ColorspaceConversion(in_raster, "rgb_to_hsv")

# Save the output
slope_hsv_3bands.save("C:/arcpyExamples/outputs/slope_hsv_3bands.tif")
